Inxi na plný plyn

Úvod

Po prvý raz som sa s tým stretol pri inštalácii Arch Linuxu. Po nainštalovaní inxi a jeho spustení s parametrom -F, teda inxi -F, kedy by výstup programu mal zobraziť maximum informácií o počítači, časť informácií bola nedostupná. A vtedy prichádza na rad použitie nasledovného príkazu:

inxi --recommends      	(pred recommends sú dve pomlčky za sebou)

nasleduje príklad výstupu z Ubuntu, ktoré má nainštalavané všetky potrebné programy, takže žiadny program nie je označený ako missing.

Výpis z inxi --recommends

inxi --recommends
inxi will now begin checking for the programs it needs to operate. First a
check of the main languages and tools inxi uses. Python is only for debugging
data collection.
---------------------------------------------------------------------------

---------------------------------------------------------------------------
Test One: Required System Directories (Linux Only).
If one of these system directories is missing, inxi cannot operate:

/proc.................................................... Present
/sys..................................................... Present

All the  directories are present.
---------------------------------------------------------------------------
Test Two: Required Core Applications.
If one of these applications is missing, inxi cannot operate:

All tests completed.

Chýbajúce programy

Všimnite si častí výpisov, kde je uvedené „All the applications are present.“. Pokiaľ by nejaké potrebné programy neboli nainštalované, v tejto časti by boli chýbajúce programy uvedené a je potrebné ich doinštalovať spôsobom obvyklým v danej distribúcii. Ako príklad uvediem doinštalovanie programu wget, ktorý bol jedným z viacerých programov, ktorý chýbal na Arch Linuxe mne.

V Arch Linuxe:

sudo pacman -S wget

V Ubuntu, Debiane, Linux Minte:

sudo apt-get install wget

Dosť často chýbajú nejaké programy z oblasti testu 4 (four). Po ich doinštalovaní je dobré si znova urobiť výpis pomocou príkazu inxi --recommends aby sme sa presvedčili, či sme na nejaký program nezabudli. Po nainštalovaní arch linuxu som musel takýchto programov doinštalovať asi desať, Ubuntu ako sa zdá z ukážkového výpisu ich má nainštalované všetky.

A teraz uvádzam príklad výpisu inxi -F po doinštalovaní všetkých odporúčaných programov na mojom počítači s Arch Linuxom. Všimnite si napríklad údaje o stavu batérie, tie sa bežne nezvyknú zobrazovať.

Ešte na ilustráciu neúplnej inštalácie uvádzam skrátený výpis z Linux Mintu, kde som skopíroval problémové miesto v teste 5 (five), kde chýba nenainštalovaný program curl.
